RUDOLPH A. MILLER, OF GALVESTON TEXAS, ASSIGNOR OF ONE-HALF OF WHIFFLETREE.

SPECIFICATION forming part of Letters Patent No. 232,999, dated October 5, 1880.

' Application filed January 5,1880.

To all whom it may concern:

Beit known that I, RUDOLPH A. MILLER, of Galveston, in the county of Galveston and State of Texas, have invented a new and useful Improvement on Swingletrees, of which the followin g i s a specification.

This invention has relation to whiiietrees; and it consists in the features of construction i and combination hereinafter fully described, 1o and particularlypointed outin the claim.

Figurel is a plan view, partly in section, of

a whiftletree embodying my improvements.

'Fig 2 is a bottom plan of a portion ot the whifiietree, showing the recess in which the base or flanged portion of the detachable eye fits. Fig. 3 is a vertical sectional view taken through the line xx in Fig. 1. Fig. 4 is a plan view ofthe detachable eye, and Fig. 5 is a side elevation of the same, a portion being broken zo away.

Referring by letter to the drawings, C designates the whiftletree, made ot'cast-steel or malleable iron, nearly crescent-shaped, and cored out at B and E to giveitlightness. The webs E, give it the requisite strength. The ends are provided with longitudinal openings G, in which screw-bolts H, provided with rings A, are secured by nuts l.

At the center of the whiiiietree U an opening or oval-shaped aperture, D, is provided,

and the under face of the whiiiletree is recessed, as at a, around the aperture D. Bolt-holes d are made through the whifiiletree near the aperturc I), as shown in Fig. 2.

A detachable eye, c, provided with a ange, b, constructed to iit the recess a, is provided with bolt-holes d2, corresponding in size and location with bolt-holes d', and is secured in bolts d, as shown in Fig. l.

The front and rear edges of the whiiiletree C are rounded, as shown in Fig. 3, in order that the animals legs may'not be cut by coming in contact therewith. The draw-pins of the cars for which this whiftletree is especially adapted pass up through the detachable eye c, and when it has become worn it may be removed and another one substituted, thus prolonging the usefulness of the single-tree for 5o years. This is equally true of the rings A. When broken they may be cheaply replaced.

I am aware that metal Whiletrees composed of two plates separated bya block and riveted together have beeny used; also, that a whiftle- 5 5 tree of wood, with a metal face-plate and a metal eye for the pin, is not new, and I do not broadly claim either of said constructions.

Having thus fully described my invention, what I claim as new, and desire to secure by 6o Letters Patent ofthe United States, is:-

As an improvementin wl1ift1etrees,the metal whiftietree C, cored out at B and E, and having the central oval opening, D, in combination with the removabie eye cb, secured in the recess a by the bolts d, and the removable rings A A, secured in the openings G by the nuts and bolts H I, substantially as and for the purposes set forth.

RUDOLPH A. MILLER.
